Answer:
The chromatin structure undergoes various modification for proper gene expression. Histone acetylation, histone deacetylation, methylation and sumoylation are important for the epigenetics.
Epigenetics may be defined as the change in the genome that affect gene activity, its expression and heritable phenotypic change of the organisms. The DNA sequence is not altered in the epigenetic modification but the gene expression has been modified by methylation or acetylation.
The statement that best describes an example of how society influences science and engineering is: Many people believe the benefits of using genetically modified organisms outweigh the risks; option A.
<h3>How should the relationship between science and society be?</h3>
“Actually, science and technology belong to society, it's the question of society itself, you can't unlink it, they are an inherent part of society. Now, how science and technology will contribute to society, this is a complex path.
With this information, we can conclude that The contribution of science to society is unquestionable, as it makes possible advances in the fields of health, food, environment, technology, energy and many others, improving the quality of life of populations and enriching societies intellectually and culturally.

(1) The varying number of muscle fibers that contract
<span>In most muscles, the number of muscle fibers in different motor units ranges from a few to hundreds. The nervous system can thus regulate the strength of contraction in a muscle by determining how many motor units are activated at a given instant and by selecting large or small motor unties to activate. </span>
some muscles are almost always partially contracted. In such muscles, the nervous system my alternate activation among the motor units, reducing the length of time any one set of fibers is contracted. Prolonged contraction can result in muscle fatigue due to the depletion of ATP and dissipation of ion gradients required for normal electrical signals.ing.
<span>(2) varying the rate at which muscle fibers are stimulated </span>
<span>single action potential produces a twitch lasting about 100 msec or less. If a second action potential arrives before the muscle fiber has completely relaxed, the two twitches add together, resulting in greater tension. Further summation occurs as the rate of stimulation increases. When the rate is so high that the muscle fiber cannot relax at all between stimuli, the twitches fuse into one smooth, sustained contraction called tetanus.</span>
Amnesia is the loss of all memory of an event of a situation. Other things that also involve loss of memory are short term memory loss, or long term memory loss
